You have a great product. Customers want it. They add it to their cart. But when they see the $600+ total, they freeze.
This price shock is the #1 killer of high-ticket eCommerce sales.
The solution isn’t to lower your prices, but instead it’s to offer installment plans.
By breaking that $600 into three manageable payments of $200 or six payments of $100, you can increase conversion rates by up to 30%.
But the secret most store owners miss is that you don’t need expensive BNPL services or clunky deposit plugins to do this.
In this guide, we’ll show you how to use a finite subscription strategy to build a frictionless, automated installment system that you control.
Why You Need Installment Plans (The Math Behind the Conversion)
Before we get into the technical setup, it is vital to understand why installment plans work. It isn’t just about affordability; it’s about perceived value and risk reduction.
When a customer sees a product for $600, their brain processes the pain of paying that lump sum immediately.
When they see “$200/month for 3 months” or “$100/month for 6 months”, the psychological barrier lowers significantly.
Data suggests that offering installment plans:
- Eliminate upfront purchase resistance: Multiple smaller payments remove the emotional barrier of a single large payment. This makes consumers in control.
- Make premium products accessible to more buyers: If you’re selling luxury items, high-value digital courses, tech gadgets, etc., installment payments instantly expand your audience.
- Increase average order value (AOV): Customers are willing to buy premium versions or add-ons when the immediate cost is lower.
- Reduce cart abandonment: Remove the price objection at the product page or checkout.
- Compete with big brands: Amazon, Apple, and Walmart all offer installment options. By running installments, your WooCommerce business is ready to compete with them.
- Build loyalty: You are offering a financial service directly to them, building trust rather than handing them off to a third-party bank.
The 2 Practical Ways to Offer Installments in WooCommerce
There are two primary ways to handle this. One is hands-off but expensive; the other is hands-on but highly profitable.
1. The finite subscription strategy
The first method is the finite subscription strategy. Instead of handing your customers off to a third-party bank, you act as the bank using a plugin.
For this, we use Sublium, a dedicated WooCommerce subscription and billing plugin. It allows you to create flexible payment plans, handle recurring billing, and automatically stop charging the customer after a set number of cycles.
How it works:
You use Sublium to create an installment plan that charges the customer’s credit card $200/month for exactly 3 months.
Pros
- Standard Stripe/PayPal fees, no BNPL surcharges
- 100% approval rate, no credit checks required
- You maintain full control of the sales experience
- Dunning, retries, invoices, and notifications are automated
Cons
- You take responsibility for payment failures (though plugins largely handle this for you)
This approach is ideal if you want to maximize margins, retain customer control, and offer flexible plans to every buyer without external approval barriers.
2. Stripe’s built-In BNPL (Klarna, Afterpay, Affirm)
If you’re using Stripe, you can enable BNPL providers directly from your Stripe settings. Customers can then choose a financing option at checkout, and Stripe handles the rest.
How it works:
The customer selects a BNPL method during checkout. The provider pays you upfront (minus processing fees) and collects payments from the customer over time.
Pros
- You receive the full payment instantly
- No collection or billing responsibilities
- Zero risk of customer non-payment
Cons
- High fees (often 4-6% + 30¢ per transaction charges)
- Customer data and experience shift to the BNPL provider
- Some buyers get rejected by the credit check, even if they have the money
BNPL is convenient, but it’s also expensive and gives away customer ownership.
Method 1: How to Set Up Finite Installment Plans in WooCommerce? (Step-by-Step)
Here is the exact process for creating an automated installment plan with Sublium, where you control the terms.
Step 1: Install and activate Sublium (all-in-one subscription plugin)
First, install Sublium, an all-in-one subscription and billing plugin for WooCommerce.
It supports finite billing cycles (weekly, monthly payments), smart retries for failed payments with support of Stripe, PayPal and Square gateways.
Make sure to activate it on your WordPress website.
Step 2: Create a WooCommerce product for installment
You can apply installments to a new product, an existing product, or a variable item.
To create one, go to Products ⇨ Add New.
Enter your product details (name, description, price, and images).
Keep it as a ‘Simple Product’ (You can add this product to the installment plan created with Sublium in the next step).
One done, publish it to create a new product.

As you can see, we’ve added a smartphone (physical item). You can even create a digital product or course.
Step 3: Add a new installment plan in Sublium
Navigate to Sublium ⇨ Plans and click on ‘Create Plan’.

Enter the name of your plan, select Installments, and click on ‘Create’ to add this plan.

Your plan will be created for a default 2-part installment payment.
Step 4: Configure your WooCommerce installment plan
Click on the plan or the pencil icon to start customizing it.

Configure the following installment options:
- Installment Count: How many payments the customer will make (e.g., 3)
- Interval: The time between each payment (e.g., 1 month).
- Plan Name: Give your plan a clear, descriptive name, such as “3-Month Payment Plan”.
- Down Payments: Optional upfront payment if you want the customer to pay a portion immediately.
- Plan Information: Use this field to describe the plan details for your customers, such as “Pay in 3 easy monthly installments of $166, no interest”.

Once configured, click ‘Update’ to save your changes.
Sublium gives you complete flexibility to add more installment plans (such as 6-month or 12-month installments) as well.
And these get added one below the other like this:

Step 5: Specify your WooCommerce product in the installment plan
On the Products tab, hit the ‘Add Product’ button.

Enter the name of your product or select a product by assigning the category.
Once you’ve selected the product, click on ‘Add’.

Sublium will automatically set the product price as per your installment plan.
You can even exclude a product from your installment plan. Plus, you can allow a one-time purchase of the product.

Click on ‘Save’ when done.
You also have the convenience of adding multiple products to a subscription plan.
Make sure to activate all installment plans in Sublium by toggling them on.

Well done, your installment plans in WooCommerce are now set up!

You’ll also receive a confirmation subscription with installment emails, which can be changed with Sublium.
Method 2: How to Set Up WooCommerce Installment Plans with Stripe BNPL Gateway? (Step-by-Step)
Follow the step-by-step instructions to offer installment payments in WooCommerce using Stripe’s built-in Buy Now Pay Later options.
Step 1: Install and activate Stripe Gateway for WooCommerce
Go to Plugins ⇨ Add New and search for FunnelKit Stripe Gateway.

Install and activate the plugin. Once done, connect Stripe with WooCommerce using a simple onboarding wizard.

These gateways operate in certain countries and currencies, such as:
- Affirm: Mainly the US and Canada
- Klarna: EU, UK, and 45+ countries
- Afterpay/Clearpay: US, Canada, UK, Australia, and New Zealand

This will enable the BNPL payment gateways in your WooCommerce store.

7 Best Practices to Follow When Setting Up WooCommerce Installment Plans
Simply enabling installment payments isn’t enough. To get the best results, your checkout should be clear, trustworthy, mobile-friendly, and fully automated.
These best practices help you reduce friction, increase conversions, and maximize revenue recovery.
1. Keep installment options simple
Offering too many payment plans can overwhelm customers. Stick to 2-4 clearly defined plans (e.g., 3, 6, or 12 monthly payments).
Always show the total price, installment amount, and duration clearly to avoid confusion.
Use phrases like “Pay $124 x 6 months, no interest!” to make the plan attractive.
You can also show pricing tables for one-time payment and installment plans to highlight the benefits.
2. Be transparent about pricing and policies
Customers should know exactly what they are committing to.
Make sure you clearly explain the monthly payment amount, the total installment amount, and what happens if a payment fails.
Sublium includes built-in payment retry and automated recovery workflows that handle most failures without manual intervention.
Also, ensure your installment structure complies with any local financial regulations.
Update your terms and conditions (T&C) to strictly outline that this is a payment plan, not a cancel-anytime rental. If a payment fails, the customer remains liable for the full balance.
3. Optimize for mobile checkout
Most eCommerce buyers shop on mobile devices, so your checkout must clearly display the payment plan on smaller screens.
Using a dedicated checkout plugin (instead of the default WooCommerce checkout) can reduce unnecessary fields, cut extra steps, and improve conversion rates.
The smoother the mobile experience, the more likely a customer complete the purchase.
4. Leverage email communication
Email plays a major role in improving installment completion rates.
Use it to confirm the plan and billing schedule immediately, send reminders before upcoming payments, and notify users if a payment fails.
Include dunning (recovery) emails with clear instructions and retry attempts. Sublium lets you customize your emails and reduces missed payments.
5. Automate where possible
Automation prevents revenue loss and reduces manual workload.
With Sublium, you can:
- Automatically process recurring payments
- Trigger retries when payments fail
- Send reminder and recovery emails
- Maintain reporting and notifications for every stage
This keeps the process smooth and minimizes administrative effort.
6. Use analytics to refine your plans
Regularly track performance to refine your offer. Monitor conversion rates for each plan, upcoming payments, failed payments, and plan cancellations.
Sublium provides built-in reporting so you can measure what’s working.
Adjust pricing, installment count, or communication strategy based on real data and not assumptions.
7. Build trust through branding
Installments require customer confidence.
Strengthen trust by including testimonials or reviews, clear refund and support policies, recognizable and secure payment options, and SSL/trust badges.
These elements reduce anxiety, especially for high-ticket products.
Key Takeaway: By keeping your installment plans simple, transparent, automated, and data-driven, you can improve checkout completion rates, reduce abandoned carts, and deliver a better overall customer experience.
Frequently Asked Questions (FAQs) on Installment Plans
Can I charge interest on these installment plans?
Yes, installment plans can include interest if you choose. Simply ensure the total cost of all payments exceeds the one-time purchase price.
For example, if the one-time price is $300, present the installment plan of 3 × $110 = $330. This ensures the total markup of 10%.
Just make sure your pricing is clearly disclosed to maintain transparency and comply with local regulations.
What happens if a customer’s card fails on the second payment?
If a recurring payment fails, Sublium will automatically trigger a dunning cycle, which typically includes multiple automated payment retries, email notifications to the customer, and a reminder message explaining what to do.
If the payment still isn’t recovered, you can configure rules such as pausing the subscription, restricting product access, or canceling the subscription entirely.
Plugins like Sublium handle this automatically, reducing manual work and lost revenue.
Do I need a credit check plugin?
No, when using the finite subscription or installment method, no credit check is usually required. Customers simply agree to the recurring billing terms at checkout.
This eliminates friction and improves conversion rates. However, it does mean you take on a small payment risk, especially for the last installments.
Is this the same as Buy Now Pay Later (BNPL)?
Not exactly, BNPL services such as Klarna or Afterpay perform their own checks, collect the payments and charge higher processing fees.
With the subscription-based installment method from Sublium, you control the payment plan, retain customer ownership, and pay the standard Stripe/PayPal processing fees.
It’s more profitable for most online stores.
Can customers check their installment schedule?
Yes. With subscription plugins like Sublium, customers can view payment schedules, update their card details, track upcoming payment dates, and view all invoice/payment history, all in their “My Account” portal.
This improves transparency and reduces support requests.
Can I require a down payment upfront?
Yes, if needed, you can add a down payment upfront to your Sublium installment plans. This reduces risk and increases cash flow.
What happens when the last payment is completed?
Upon the payment of the last installment, the plan completes automatically, and the subscription is marked finished. There’s no need for manual intervention.
Does this work for digital products, physical items, and services?
Yes. Installment plans can be used for online courses, coaching programs, high-ticket physical products, subscriptions with fixed cycles, and memberships with defined terms.
Just ensure your fulfillment model aligns with the timing of revenue collection.
Which plugin should I use to set this up?
Tools like Sublium, WooCommerce Subscriptions, and others all support installment plans, but they differ in:
- How they handle expiration
- Whether dunning automation is included
- How down payments are configured
- Reporting capabilities
- Ease of setup
If you share your budget and technical skill level, I can recommend the best plugin for your stack.
